Product Description:

Specifications: BVVB

Voltage levels: 300/500 v

Execution standard: JB/T8734-2012

Scope of application: this product is used ac rated voltage up to and including 450/750 (U0 / U) power, electrical appliances, instrumentation and telecommunications equipment.

Using features: 1, the cable of rated voltage U0 / U for 300/500 v. 2, long-term allowed working temperature does not exceed 70 ℃. More than 3, short circuit temperature: cable or multicore cable short circuit occurs (the longest duration of no more than 5 s), the highest temperature conductor does not exceed 160 ℃. 4, installing a wire laying, bending radius should be greater than the specified value. Diameter greater than 25 mm above the wires, bending radius should not less than 6 times of cable diameter. Diameter is less than 25 mm below the wire, bending radius should not less than 4 times of wire diameter. 5, PVC insulated and sheathed wire and cable laying, environment temperature should not be below 0 ℃. 6, plastic insulated wire such as BV cloth when installing laying wires, if wear pipe laying, should give full consideration to the diameter of the plastic pipe size, pipe threading the total cross section should be not more than 40% of the plastic tube hole section, for the normal operation of electric wire have plenty of room cooling, installation and wire laying should be far away from heat source.

Key performance indicators: 1, the conductor when 20 ℃ maximum dc resistance, 24.5 Ω/km. 2, the ac voltage 2500 v, 5 minutes not breakdown.

Q:Ask you a question: how the computer CD-ROM power supply 5V and 12V two lines? Another audio and video cable which group?
My computer --- right-click properties. Device Manager. Look at the USB device is not there or the number. Have to reinstall the system. Also make sure your motherboard USB interface is not good. I said the interface is plug USE jumper of the root.
Q:Calculate the control cable under what circumstances the cable terminal needs to be calculated
This is the air defense when the air pipe laying through the mouth of the closed wall or the protection of closed wall approach, regardless of the side of the wall or the roof into the line have this requirement
Q:A sub-eight splitter, behind the link ONU equipment, which also need to add fiber patch panels, or can be directly connected?
Cabinets Half Week + Line (Horizontal + Vertical) + End Range Cabinets Half Week Long or Longer to Equipment Reserve + Quota Total Length * 2.5%
Q:The UV lamp is fitted with ozone and no ozone difference
. like the computer boot fast, the best way is solid state hard drive, followed by the win. the system is very good, the interface is also familiar with the boot fast, especially the new browser edge than a lot stronger; . if you now computer The monitor is also good, and now the computer's hard drive can be taken down to the new computer above, then 3000 yuan can buy very very good, desktop. If the notebook is about 4500 or so relatively high cost. . do not recommend the configuration of their own one by one to buy accessories, it is recommended that you look at the top of the machine installed Taobao business, they rely on the volume, not only to ensure that the genuine accessories, the price is relatively cheaper to buy their own, And wiring installation are also professional. And they are equipped with win7 is free to upgrade to win. very good. I just bought a few days ago a machine, monitor and hard drive or use their original, with the host with the solid-state hard drive as a boot disk, their hard drive as a storage disk, spent a total of . the performance is very good.
